Abstract

A method of analyzing metal oxides. In this method, metal oxide is provided, heated with microwaves, and a conductivity parameter of the metal oxide is determined. From the conductivity parameter, a determination is made regarding a pyroelectric effect of the metal oxide.

Claims

exact text as granted — not AI-modified
1. A method of analyzing a metal oxide, said method comprising the steps of:
 heating said metal oxide with cumulative microwave exposure; 
 measuring a thermal response of said metal oxide to said microwave exposure; 
 correlating said thermal response to a conductivity of said metal oxide; and 
 correlating said conductivity to a pyroelectric effect of said metal oxide. 
 
     
     
       2. The method of  claim 1 , wherein said thermal response is a temperature. 
     
     
       3. The method of  claim 1 , wherein said step of heating said metal oxide comprises intermittent heating. 
     
     
       4. The method of  claim 1 , wherein said metal oxide is coated. 
     
     
       5. The method of  claim 1 , wherein said metal oxide is uncoated. 
     
     
       6. The method of  claim 1 , wherein said metal oxide is dispersed in a solvent. 
     
     
       7. A method of analyzing zinc oxide, said method comprising the steps of:
 heating said zinc oxide with cumulative microwave exposure; 
 measuring a thermal response of said zinc oxide to said microwave exposure; 
 correlating said thermal response to a conductivity of said zinc oxide; and 
 correlating said conductivity to a pyroelectric effect of said zinc oxide. 
 
     
     
       8. The method of  claim 7 , wherein said zinc oxide is n-doped. 
     
     
       9. The method of  claim 7 , wherein said zinc oxide is selected from the group of coated zinc oxides and uncoated zinc oxides. 
     
     
       10. The method of  claim 7 , wherein said zinc oxide is dispersed in a solvent. 
     
     
       11. The method of  claim 7 , wherein said step of heating said zinc oxide with microwave exposure is intermittent heating.
